Scans of the Palomar-Leiden Trojan Survey Plates

I. Van Houten-Groeneveld, C.J. Van Houten, M. Wisse-Schouten, C. Bardwell & T. Gehrels
This service publishes plate scans of the Palomar-Leiden Troian surveys conducted between 1960 and 1977. The surveys led to the discovery of more than 2,000 asteroids (1,800 with orbital information), with another 2,400 asteroids, including 19 Trojans, found after further analysis of the plates. Note that because of the large size of the plates, in this service each original plate is contained in two parts, marked with "_1" and "_2", respectively. The central parts of...

Magellanic Clouds Extinction Values

R. Haschke, E.K. Grebel & S. Duffau
A catalogue of E(V-I) extinction values is presented for 3174 (LMC) and 693 (SMC) fields within the Magellanic Clouds. The extinction values were computed by determining the (V-I) colour difference of the red clump from Optical Gravitational Microlensing Experiment (OGLE III) observations in the V and I bands and theoretical values for unreddend red clump colours.

ARI Catalog of Catalogs

ARI katkat is a catalog of star catalogues in the spirit of G. Teleki's catalog of star catalogs (`1989BOBeo.140..131T`_ and references in there). It contains 2573 catalogs suitable for astrometric usage, starting with Flamsteed (1835) and ending in the 1970ies. For almost all of them, there is a column description file (as PDF, and unfortunately sometimes in German) and the digitized content. .. _1989BOBeo.140..131T: http://ads.g-vo.org/abs/1989BOBeo.140..131T

TOPCAT and Aladin working together

G. Iafrate, M. Ramella, K. Riebe, F. Rothmaier, M. Demleitner & S. Gabriel
This tutorial will show how tabular data can be easily transferred from Topcat to Aladin or the other way, and it will illustrate the benefits of this inter-client communication for VO users. This is shown with a quick look at filtering members of the Coma Cluster from SDSS.

Adding catalog data to object lists using the VO

M. Demleitner
This brief tutorial shows you how to quickly add proper motions and photometry from Gaia to (almost) any object list using the Virtual Observatory. The VO protocol most suited to this kind of this is TAP ("table access protocol") and lets you transfer data and queries to database servers. In the example, we will be using TOPCAT as a client. There is no lock-in to it: There are libraries and other tools allowing an integration...

The HSOY Catalog

M. Demleitner, S. Röser, M. Altmann, U. Bastian & E. Schilbach
HSOY is a catalog of 583'001'653 objects with precise astrometry based on PPMXL and Gaia DR1. Typical formal errors at mean epoch in proper motion are below 1 mas/yr for objects brighter than 10 mag, and about 5 mas/yr at the faint end (about 20 mag). South of -30 degrees, astrometry is significantly worse. HSOY also contains, where available, USNO-B, Gaia, and 2MASS photometry. HSOY's positions and proper motions are given for epoch J2000. The...

Gaia eDR3 Autocorrelation

M. Demleitner
This is a table that simply gives, for each object in Gaia eDR3, the identifier of its closest neighbour together with the distance of the pair.

Gaia DR3 MC sampled XP spectra SSA

M. Demleitner & R. Andrae
This is a re-publication the Gaia DR3 RP/BP spectra in the IVOA Spectral Data Model. It presents the continous spectra in sampled form, using a Monte Carlo scheme to decorrelate errors, elaborated in this resource's reference URL. The underlying tables are also available for querying through TAP, which opens some powerful methods for mass-analysing the data.

Corrections between USNO-B and PPMXL

S. Röser, M. Demleitner, E. Schilbach & J. J. Vickers
Differences between USNO-B and PPMXL in positions and proper motions, on an all-sky one-degree grid. At each gridpoint we give the differences X(PPMXL)- X(USNO-B1.0) averaged over all stars in a sqrt(2)/2-degrees environment around the gridpoint given. The corrections given here should bring USNO-B based astrometry to the ICRS.

Flash/Heros SSAP

B. Wolf, A. Kaufer, H. Mandel & O. Stahl
Spectra from the Flash and Heros Echelle spectrographs developed at Landessternwarte Heidelberg and mounted at La Silla and various other observatories. The data mostly contains spectra of OB stars. Heros was the name of the instrument after Flash got a second channel in 1995.

Gaia early DR3 Mock Catalogue (gedr3mock)

J. Rybizki, M. Demleitner, C. Bailer-Jones, P. D. Tio, T. Cantat-Gaudin, M. Fouesneau, Y. Chen, R. Andrae, L. Girardi & S. Sharma
This catalogue is a simulation of the Gaia EDR3 stellar content using Galaxia (a tool to sample stars from a Besancon-like Milky Way model), 3d dust extinction maps and the latest PARSEC Isochrones. It is mimicking the Gaia DR2 data model and an apparent magnitude limit of G=20,7. Extinctions and photometry in different bands have also been included in a supplementary table as well as uncertainty estimates using scaled GDR2 errors. Additional magnitude limit per...

HDAP -- Heidelberg Digitized Astronomical Plates

H. Mandel, K. Birkle, M. Demleitner &
Scans of plates kept at Landessternwarte Heidelberg-Königstuhl. They were obtained at location, at the German-Spanish Astronomical Center (Calar Alto Observatory), Spain, and at La Silla, Chile. The plates cover a time span between 1880 and 1999. Specifically, HDAP is essentially complete for the plates taken with the Bruce telescope, the Walz reflector, and Wolf's Doppelastrograph at both the original location in Heidelberg and its later home on Königstuhl.

Outlier Analysis in Low-Resolution Spectra: DFBS and Beyond

M. Demleitner, A. Mickaelian, A. Knyazyan, D. Baghdasaryan & G. Mikayelyan
Low-resolution spectra like those resulting from objective prism observations or the RP/BP instrument on board of the Gaia astrometry satellite enable a wealth of interesting science. This use case investigates one use leading up to combining many VO resources: The identification of misclassified objects from reference databases.

Explore the Pleiades with TOPCAT and Aladin

M. Demleitner & H. Heinl
As stars in open star clusters are formed from the same matter at the same time and have only a small velocity dispersion, it is relatively easy to identify them from the background stars. In this tutorial, we will identify the members of the Pleiades kinematically and get an idea of our success by examining a color-magnitude diagram using TOPCAT, Aladin, and a few VO services.

A Gaia DR2 mock stellar catalog

J. Rybizki, M. Demleitner, M. Fouesneau, C. Bailer-Jones, H.-W. Rix & R. Andrae
This catalogue is a simulation of the Gaia DR2 stellar content using Galaxia (a tool to sample stars from a Besancon-like Milky Way model), 3d dust extinction maps and the latest PARSEC Isochrones. It is mimicking the Gaia DR2 data model and an apparent magnitude limit of g=20,7. Extinctions and photometry in different bands have also been included in a supplementary table as well as uncertainty estimates using a scaled nominal error model.

Plate Scans in the VO

M. Demleitner
This tutorial introduces a few techniques for working with image services in the Virtual Observatory (VO) in general, using services containing plate scans as examples. It will discuss both exploratory, interactive use, and scripting using pyVO.

The PPMXL Catalog

S. Röser, M. Demleitner, E. Schilbach & J. J. Vickers
PPMXL is a catalog of positions, proper motions, 2MASS- and optical photometry of 900 million stars and galaxies, aiming to be complete down to about V=20 full-sky. It is the result of a re-reduction of USNO-B1 together with 2MASS to the ICRS as represented by PPMX. This service additionally provides improved proper motions computed according to Vickers et al, 2016 (:bibcode:`2016AJ....151...99V`).

The LIFE Target Star Database LIFETD

F. Menti, S. Quanz &
The LIFE Target Star Database contains information useful for the planned LIFE mission (mid-ir, nulling interferometer in space). It characterizes possible target systems including information about stellar, planetary and disk properties. The data itself is mainly a collection from different other catalogs. Note that LIFE's target database is living data. The content – and to some extent even structure – of these tables may change at any time without prior warning.

Deep Mosaic of the Fornax cluster core

T. Lisker, C. Wittmann, A. Pasquali, M. Hilker, E.K. Grebel & A. Venhola
This is a deep optical mosaic of the Fornax cluster’s core, covering 1.6 square degrees. The data were acquired with ESO/MPG 2.2m/WFI, using a transparent filter that nearly equals the no-filter throughput and thus provides a high signal-to-noise ratio. Based on an approximate conversion to V-band magnitudes, the unbinned and binned mosaics (0.24 and 0.71 arcsec/pixel) reach a median depth of 26.6 and 27.8 mag/sq.arcsec, respectively.
